10 Most Common Furnace Repairs: What You Need to Know

Are you having trouble with your furnace? If so, you're not alone. Many homeowners experience furnace problems from time to time. To help you out, here is a comprehensive guide to the 10 most common furnace repairs and what you can do to fix them. The first issue is a faulty thermostat.

If your thermostat isn't working properly, it can cause your furnace to run inefficiently or not at all. To fix this, you'll need to replace the thermostat or have a professional do it for you. The second issue is a flickering, faint, or strangely colored pilot light. This could be caused by a dirty pilot light or a faulty thermocouple.

To fix this, you'll need to clean the pilot light and/or replace the thermocouple. The third issue is strange odors coming from the boiler. If it smells like something is burning or of gasoline, you'll want someone to come check it out right away. If you smell something like rotten eggs, the best option is to get out of the house as quickly as possible and call 911, especially if you have propane.

The fourth issue is an inefficient gas boiler. To reduce energy costs and prevent damage to your boiler, opt for a gas boiler that turns on and off frequently or has short cycles. If your boiler is running more than usual when it's very cold outside, this activity can be normal and necessary to keep the house at a comfortable temperature. However, if it's running more than usual when it's not cold outside, this could indicate a problem with the boiler.

The fifth issue is a dirty filter. A dirty filter can cause your furnace to run inefficiently and can even cause it to shut down completely. To fix this, you'll need to replace the filter with a new one. The sixth issue is a clogged exhaust vent.

This can cause your furnace to overheat and shut down. To fix this, you'll need to clean the exhaust vent and make sure it's clear of any debris or blockages. The seventh issue is a faulty blower motor. If your blower motor isn't working properly, it can cause your furnace to run inefficiently or not at all.

To fix this, you'll need to replace the blower motor or have a professional do it for you. The eighth issue is an old furnace. An old furnace can be inefficient and may need frequent repairs. If your furnace is more than 10 years old, it may be time to consider replacing it with a newer model. The ninth issue is an undersized furnace. An undersized furnace won't be able to keep up with your home's heating needs and will need frequent repairs.

To fix this, you'll need to install a larger furnace that can handle your home's heating needs. The tenth issue is an improperly installed furnace. If your furnace was installed incorrectly, it won't be able to operate efficiently and will need frequent repairs. To fix this, you'll need to have a professional come in and inspect the installation. If you're having any of these issues with your furnace, it's best to call in a professional for help. Trying to repair anything inside or outside the boiler yourself is not recommended, as it could be very dangerous if you don't have the necessary professional training to work on air conditioning equipment.
